Our solar system is a late comer in a galaxy which had metal-rich systems billions of years earlier. Assuming life happens elsewhere, by whatever means, there were probably civilizations with billion-year histories already in place before the solar system formed. In that span of time the possible extent of technological development is virtually unlimited. For all we know, the solar system and our Earth-Moon habitat was artificially crafted from natural elements like a Japanese garden.
That scenario might be the only explanation for the Moon, which otherwise should not exist at all, especially where it is now.

The problem with that is the universe is just too small and way too young for for random chance to be a mechanism. DNA is based on a 22 “letter” code, and therefore cannot evolve. The math on these theories blew up 40 years ago. That’s why many microbiologists and organic chemist skirt the issue, (to protect their careers.) The nature of information as well as the mathematical study of randomness completely destroy the theory. Not to mention that it violates basic physical laws....just sayin.
